Find the tension in each cable Physics Problem -

AI Thread Summary
The problem involves calculating the tension in three cables supporting a 162.4-N bird feeder. The left cable has a tension of 140 N, the right cable has 80 N, and the bottom cable carries the full weight of 162.4 N. The solution emphasizes that the net force is zero, indicating static equilibrium. To find the tension in each cable, one must analyze the component forces acting on the system. The discussion concludes with a successful resolution of the problem.

The question states that the bird feeder is supported by the three cables. This implies that the net force is zero. Hence find expressions for each component force and continue from there.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
